About it

Plain yogurt is the reference point for all yogurts: milk plus Streptococcus thermophilus and Lactobacillus bulgaricus, the two cultures required for the name yogurt in the United States. Everything else in the category is a variation on it.

Storing it

A layer of whey on top is normal; stir it in. Plain yogurt freezes for up to 2 months for cooking and smoothies.

Using it

Stir plain yogurt into curries and sauces off the heat so it does not split. Use it in marinades, dressings, and baking in place of buttermilk.

Swaps & pairings

Greek yogurt swaps in where body matters. Sour cream covers cooked savory dishes with more fat and less tang.
